Jarvis Jones has confirmed that he is still working through the NFL's concussion protocol.
The Pittsburgh Steelers rookie linebacker was diagnosed with the concussion after complaining of a headache following the 19-6 win over the New York Jets last week.
The 23-year-old told the team's official website: "We're still taking precautions and going through the steps, doing the right thing. We're just taking it slow. Still have two more days before Sunday. We're gonna see what they say.
"Sunday night I got home around 8, and I went to sleep when I got home. I was tired. I woke up Monday with a headache.
"I feel good today. I got out there and I ran around and did some things. I'm feeling fine, just waiting on being able to go through this process and see what happens."
Jones is listed as questionable for the team's game against the Baltimore Ravens tomorrow.
